Justice League of America: Tower of Babel by Mark Waid
When Batman's arch enemy, the immortal mastermind R'as al Ghul, resurfaces with a terrifying plan to destroy all means of communication, including the spoken word, the world's mightiest heroes - Superman, Batman, Wonder Woman and Green lantern - rally to stop him. But it soon becomes apparent that not all of their number has the same agenda. For one hero the battle is far more personal, and he'll do anything - including betray his teammates - to see final justice done. Whatever the outcome, the JLA will be changed forever!
